For such an old car, which gets such a hammering (it lives in London and does a 55 mile round trip to work every day), it's fantastic. Pretty economical on long runs, and OK round town, it's always been totally reliable - apart from the above faults. My dad had it from 50 000 miles onwards, and it was good as gold for him, too.
Galvanised, so there's no rust. The only gripe is the ludicrous boot. Oh, and the heated rear windscreen, which keeps breaking.
